Is "AIAngel" (Patreon) a fake?
No, AiAngel is not a bot.
It's Rouge's software that changes his voice along with facial recognition software which tracks his movement and copies it to the avatar.

That being said, he has created a very entertaining channel and line of work for himself. By looking at the videos, you can see that he is a true genius at work. Single handedly puts on all hats for that project, from hardware infrastructure development, to software design to graphic art to acting and video editing. Truely one of the great minds of this era.
